BOSTON (AP) -- A 102-year-old woman prosecutors say killed her 100-year-old roommate in a Massachusetts nursing home nearly five years ago still faces a second-degree murder charge.

Laura Lundquist is the oldest murder defendant in state history.

Lundquist was 98 when she was charged in 2009 for allegedly strangling Elizabeth Barrow, who was found with a plastic bag tied around her head at the Brandon Woods nursing home in Dartmouth.

Lundquist had a longstanding diagnosis of dementia and was ruled incompetent to stand trial. Since her indictment, she has been held at a state psychiatric hospital, while the murder charge against her remains active.

The Massachusetts Appeals Court is expected to rule soon on an appeal from Barrow’s son in his wrongful death lawsuit against the nursing home. An arbitrator dismissed the suit.
